The video can be watched on You-Tube at https://www.youtube.com/watch?v=_de3HJvO-N8&safety_mode=true&persist_safety_mode=1 In addition to watching the video, visit the Sports Science Exploratorium at http://www.exploratorium.edu/explore/staff_picks/sports_science/

In your posting, be sure to:
1. Identify the IV, DV, hypothesis, 2 constants, and 2 possible sources of error for the experiment. In addition, suggest a title for the experiment.
2. Discuss something you found interesting at the Sports Science Exploratorium. Share it with your classmates, being sure to explain how it pertains to science.

1.
IV: type of ball and speed of ball.
DV: difficulty of hitting
Constants: Jenny Finch (person throwing ball) brand of ball, distance to throw ball.
Errors:
1.Two IV's are tested.
2. Distance changes.

I guess u r right , they first tested the force and speed and then later they tested the reaction time. They used these two sources to find which is harder to hit. it's little bit confusing cos they used two variable(basses ball n softball) to find the first IV(force n speed)

IV: different amount of water
DV: plats height
2 controlled variables: type of water used, time of day when the plants are watered
Sources of error : the temperature is too high and some water evaporates, using a smaller container for one of the plants making it difficult to grow.
Hypothesis: if the amount of water increases then the plants height increases
I guess this is what we had to do for today

IV- speed and type of ball
DV-which is harder to hit
Constants- person hitting the ball, person throwing the ball (Jennie Finch, and the other guy)
Sources of error- Jennie Finch standing closer to the hitter than the baseball guy. (Even though that's how you play baseball, it still didnt seem right)
Title- Effect of ball type on batting difficulty

2. At the Sports Science Exploratorium, I did not look at sports, but I did look at Science, and found my age on different planets...and I won't live to see my first birthday!

On PLuto: I am 944.3 Plutonian days, and 0.069 Plutonian years, and my next birthday is on Tuesday, March 29, 2242!

This pertains to science because I am showing how different planets that are farther away from the sun, have long revolutions that Earth's 365 days.

IV: Type of ball..baseball or softball
DV: Accuracy in hitting the ball
Hypothesis: If the type of ball changes then the accuracy in hitting the ball will change
Constants:Same person pitching the ball, Skill level of the hitter.
Sources of error: High number of pitches(whether the pitcher was fatigued or not), Different type of bat

I found the science part of it all interesting. Only because when you play a sport you dont necessairly think about the science of it all. From the muscles being used together and the angles in which something (i.e the ball) is being hit. I think this relates to science when you break it down because without the muscles in your body you wouldnt be able to techincially do anything in a sport.
I also loved the article on the different parts of a skateboards and stuff. Im not a big skateboard person but it seemed like it would be a chance to learn something new and i did. The whole thing about a skateboard deck being made of maple is awesome!!

Part Two: I found it interesting that in the 1870s women played in an outfit that weighed as much as 30 pounds and included a floor-length skirt, underskirts, a long-sleeved, high-necked blouse, and high button shoes.
